Description
Technical field
This utility model relates to a kind of stake mechanomotive force head, particularly relate to the impacter on a kind of machine matching used enter rock drill bit structure.
Background technology
During pile foundation construction, it is necessary to using to stake machine, stake machine drives bit by power set, and ground is carried out pile boring, rock stratum as harder in run into ground, impacter on existing stake machine supporting enter rock drill bit structure rate of penetration slowly, inefficiency.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of enter impacter on rock speed is fast, efficiency is high stake machine matching used enter rock drill bit structure.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: enter rock drill bit structure, including: enter rock drill bit and be arranged on the interior drill bit into rock drill bit internal, the middle part of described interior drill bit is provided with air flue, the insufflation channel hole that some and described air flue lower end is connected it is evenly arranged with in the conical nose of interior drill bit lower end, described insufflation channel hole is connected with the internal cavities entering rock drill bit, the conical nose surface of described interior drill bit lower end is provided with some interior drill bit alloy tooth protection, described enter the inwall of rock drill bit and lower end head are both provided with some enter rock drill bit alloy tooth protection, described enter rock drill bit lower end head on be evenly arranged with some anti-dregs breach, enter rock drill bit is provided with the anti-dregs air flue that some and anti-dregs breach is connected described.
The utility model has the advantages that: above-mentioned enter rock drill bit structure, simple in construction, it is possible to is holed in relatively harder rock stratum, rock can be smashed rapidly, carg after smashing can be conveyed out outlet easily, enters rock stratum relatively easy, and work efficiency is high.

Detailed description of the invention
Particular content of the present utility model is described in detail below in conjunction with the drawings and specific embodiments.
Such as Fig. 1, Fig. 2, shown in Fig. 3, enter rock drill bit structure, including: enter rock drill bit 1 and be arranged on into the interior drill bit 2 within rock drill bit 1, the middle part of described interior drill bit 2 is provided with air flue 3, the insufflation channel hole 5 that some and described air flue 3 lower end is connected it is evenly arranged with in the conical nose 4 of interior drill bit 2 lower end, described insufflation channel hole 5 is connected with the internal cavities 6 entering rock drill bit 1, conical nose 4 surface of described interior drill bit 2 lower end is provided with some interior drill bit alloy tooth protection 7, described enter the inwall of rock drill bit 1 and lower end head are both provided with some enter rock drill bit alloy tooth protection 8, described enter rock drill bit 1 lower end head on be evenly arranged with some anti-dregs breach 9, enter rock drill bit 1 is provided with the anti-dregs air flue 10 that some and anti-dregs breach 9 is connected described.
As shown in Figure 3, above-mentioned enter rock drill bit structure install time, the upper end of interior drill bit 2 is connected with the lower end of impacter 13 with boring centring ring 12 by drive joint 11, oversheath 14 is arranged on the outside of impacter 13, oversheath 14 is evenly arranged with spiral conveying blade 15, during use, enter the continuous bob impact of piston 16 that rock drill bit 1 is subject in the impacter 13 that its top compression air is power.It is subject to the drive joint 11 that unit head drives to rotate and carry out rock stratum and impact cutting simultaneously, cut into cylindrical rock 18 and be subject to conical nose 4 broken of interior drill bit 2, quickly become dregs, compression air is entered internal cavities 6 by air flue 3, insufflation channel hole 5 its inside dregs is jetted, dregs after pulverizing passes through anti-dregs breach 9, anti-dregs air flue 10, is conveyed out aperture under the effect of spiral conveying blade 15.
Above-mentioned enter rock drill bit structure, simple in construction, after make use of rock stratum to be cut into single cylinder, breakable principle carries out rock stratum and creeps into, and work efficiency is high.
